Here is a project through AMATYC that provides some resources for excellent problem solving tasks. These problems could be accessible to students at the intermediate algebra level and would be good resources for a MATHWAY or STATWAY course. The project is called The Right Stuff and you can find a link here AMATYC The Right Stuff
